GASKET PLATE
A gasket plate having a rigid orientation plate retaining at least one seal in a predetermined location in the orientation plate, and a rigid insert placed inside the seal such that the seal interposes the insert and the orientation plate.
1 . A gasket plate comprising:
a rigid orientation plate retaining at least one seal in a predetermined location in the orientation plate; and
a rigid insert placed inside the seal such that the seal interposes the insert and the orientation plate and defines a passageway through the orientation plate.
2 . The gasket plate of claim 2 , wherein the seal defines an outer tongue fitting into a groove defined in the insert.
3 . The gasket plate of claim 2 , wherein the seal comprises rubber and is vulcanized to the insert.
4 . The gasket plate of claim 2 , wherein the seal defines an inner tongue fitting into a groove defined by the orientation plate.
5 . A gasket plate comprising:
a planar orientation plate having a thickness and defining a passage through the thickness, the passage defining a passage wall;
an elastomeric seal abutting the passage wall; and
a rigid, annular insert contacting the elastomeric seal and retaining the seal against the passage.
6 . The gasket plate of claim 5 , wherein the elastomeric seal comprises a rubber and is vulcanized to the insert.
7 . The gasket plate of claim 5 , wherein the insert stretches the elastomeric seal and presses it into the passage wall.
8 . The gasket plate of claim 5 , wherein the passage wall defines a groove that receives at least part of the elastomeric seal.
9 . The gasket plate of claim 8 , wherein the elastomeric seal provides a tongue fitting into the passage wall.
10 . The gasket plate of claim 5 , wherein the rigid insert defines a groove that receives part of the elastomeric seal.
11 . The gasket plate of claim 10 , wherein the elastomeric seal defines a tongue fitting into the groove of the elastomeric seal.
12 . A gasket plate comprising:
an orientation plate having a thickness and a passage defined therethrough;
an elastomeric seal in the passage;
a rigid, annular insert contacting the elastomeric seal and preventing collapse of the elastomeric seal away from a passage wall; and
means for preventing slippage of the elastomeric seal against the passage wall.
13 . The gasket plate of claim 12 , wherein the means for preventing slippage of the elastomeric seal against the passage wall comprises a textured surface on the passage wall.
14 . The gasket plate of claim 12 , wherein the means for preventing slippage of the elastomeric seal against the passage wall comprises a tongue and groove arrangement between the elastomeric seal and the passage wall.
15 . The gasket plate of claim 12 , further comprising means for securing the elastomeric seal to the insert.
16 . The gasket plate of claim 15 , wherein the means for securing the elastomeric seal to the insert comprises vulcanizing the elastomeric insert to the insert.
17 . The gasket plate of claim 15 , wherein means for securing the elastomeric seal to the insert comprises a tongue and groove arrangement between the elastomeric seal and the insert.
18 . The gasket plate of claim 12 , wherein the elastomeric seal is annular.
19 . The gasket plate of claim 18 , wherein the elastomeric seal defines inner and outer tongues fitting into a groove defined on the insert and a groove defined in the passage wall, respectively.
20 . The gasket plate of claim 19 , wherein the elastomeric seal defines upper and lower tongues on upper and lower surfaces thereof, respectively, facing away from a plane of the orientation plate.
